Colors that go with Substack Accent
Charcoal, Light Sea Green and Amber lead the list. Each partner is a real named colour with the reason it works — a wheel relationship, a neutral that carries it, or a pairing lifted from a palette or brand system that actually shipped — and every pair opens in the palette tool.
Charcoal #36454f
neutralshippedCharcoal is the body-text near-black for Substack Accent: its slight blue cast keeps type crisp beside a warm colour where pure #000 looks heavy.
Light Sea Green #20b2aa
complementaryshippedLight Sea Green sits directly opposite Substack Accent on the wheel — the strongest contrast one hue can give another, so use it small: a button, a link colour, one highlight.
